Hire a pretty, young girl to talk about your ideas and products or services like as if it's her own original concept.
Boom. instant YouTube success. (or hire a pretty young male)

Ebay and PayPal fees, and Google Adsense and Youtube fees/commisions, and talent and sports Agents...All take a huge chunk out of your success. They are like the IRS...they will bleed you dry.

It tough to be an online sensation...you need like literally hundreds of millions of page views just to generate a somewhat decent, happy income.
With trading, a single hermit no one has seen or talk to...can generate mountains, or millions.
